AUTO-HEATER.

'Patented Nov. 14, 191e.

Application led March 8, 1916. Serial No. 82,989.

which air is used as a cooling mediumv forA the circulating water on water jacketedengines. We further may` supplement this by causing this circulating air to encounter and pass around the exhaust' pipe to additionally!v heat it.-

The main object of our Vinvention resides in the combination with the floor board of an automobile having an opening therein, of a grid and deflector plate structure arranged tooperate in conjunction with the opening to permit the flow of. air into the interior of the vehicle or to exclude the same as may be desired, depending upon the 'atmospheric condition.

. A further object of our invention resides in the provision of a register structure embodying a cowl structure coperatively mounted with respect to the exhaust pipe, which cowl structure is provided with an opening arranged to permit thedirect flow of air through the same when the deflector structure is in -a position of closure over the register as a whole. However, when the deiiector is in the opposite position, the cowl opening is covered to thereby deflect all of the heated'air into the interior of the' ear.

The'preferred embodiment of our invention is shown in the accompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

' Figure 1 yis a sectional vie w showingay portion of anlautomobile engine and body with our heater structure applied thereto. Fig. 2 is a top view looking down onto .the

footboard structure :1S-shown in Fig. 1. Fig. 3`is a view of the same structure but looking from the bottom, and, Fig. l is a cross section taken on line 4 4 of Fig. 3.

In Fig. 1, the automobile body is designatgd generally bythe reference numeral 1 E. STRAIN and is shown as' being providedwith an en-I gine 2 having an exhaust pipe 3. The bot; Y

tom of the vehicle is provided with a foot board shown at 4 and it is in connection with this footboard that our invention is applicable. This foot board is provided with a out out portion or opening 5 which' -1s covered by means of a grid shownv at 6.

To the underside of this foot board there vis attached a cowl structure 7 which cowl is. preferably formed of sheet `metal bent to present two sides and a bottom as is shown. The bottom is .cutout as at 8 to lit over the exhaust pipe '3 in the relation shown and is further provided with a cut out por' tion through the greater portion of its area asis shown at 9. Mounted inY cooperative'- relation with this opening 9 and the grid structure 6 is a deflector plate 10-pivotally supported as shown at 11 to the cowl itself.

Fromthe arrangement shown in Figs. 1`

and 4, it will appear that whenthe deflector 'plateis in its lowered position, the draft of air coming through the radiator will circulate about the engine and-the exhaust pipe and enter thelcinterior of the vehicle. However, when this defiector plate structure is swung about its pivot to assume a position of closure'with respect to the grid structure or as is indicated in dotted lines in Figs. l

and 4, the draft of air is prevented from coming into the interior of the vehicle, but passes through the opening 9.

The deflector plate is preferably moved to lowered position by means of the locking memberk shown' at 12, which member is 4provided with a series of ratchet teeth 12a. The

' locking member'itself is pivotally supported 'as at 13'in connection with the deflector plate and pressure upon the foot plate 14 located on its outer end will force the deflector plate to the position shown in full lines in Figs.` l ande and this position may bemaintained by'causing the last toothl2 t0 engagethe -underside of the grid structure. However,

this deflector plate is moved vto this position against the pressurefof a leaf spring as shown at 15, which leaf spring acts to urge the delector plate toits elevated position or ,the position shown in broken lines. Therefore, release of the locking member from 'its position of engagement' as isl shown, will automatically move the defleotor plate to the dotted line position.

From theforegoing description, it will be apparent that we have provided a very uSe- Jul structure for keeping the occupants of a motor vehicle warm during the winter months. Further, this device may be applied with comparative ease and further, does not render any of the working parts of the vehicle inoperative.

VVhat'We claim is:

l. The combination with the foot board of an automobile having an openingv'therein, of a grid covering said opening, a cowl coperatively mounted with respect to the engine exhaust pipe, said cowl having an opening in its rear wall, and a movably sup.

ported deflector plate movable to assume position covering either the opening in said cowl or said grid.

2. The combination with the foot board of an automobile having an opening therein,

engine exhaust pipe, said cowl having an' opening in its rear wall, a pivotally suppdijted deflector plate movable to assume position covering either the opening in said cowl or said grid, means for locking said plate in one of said positions, and spring means for urging said plate to assume the other position.

In testimony whereof we aflix our signatures in presence of two witnesses.
